l IMPROVEMENT IN PUMPS.

Specification forming part of Letters PatentNo. {NLR/13, dated May 18, 1869.

g To all whom tmayconcer/n:

Be it known that I, ,PARKER WINEMAN, of Joliet, in the county4 of Will `and State of Illinois, have invented a new and Improved Bump; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyingdrawings, making part of this specification, in whichv Figure lisa vertical central section through my improved pump, showing the piston or bucket in the act of descending. Fig. 2 is an enlarged central section through the metallic section and portions of the Wooden sections of the pump, showing the bucket or piston in the act of ascending. Fig. 3 is a section taken through the pump in the horizontal plane in dicated by line y y, Fig. 2. Y

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to certain novel improvements on Wooden pumps; and consists, first, in constructing one of the sections or lengths of the pump-stock of metal, lined with a vitreous enamel, to present a smooth, durable "surface to the pump-bucket or pistonpack-ing, and adapted to receive Within its ends the tapering ends of the wooden sections, and thus serve as a coupling for these sections, as Will be hereinafter explained; second, in an annularlygrooved ring-piston, which has coniined within its groove a suitable packing, and which is constructed with an annular valveseat on its upper side, adapted for a circular valve which moves freely upon a central valvestem, as will be hereinafter explained.

To enable others skilled in the art to under stand my invention, I will describe its construction and operation.

In the accompanying drawings, A B G represent three hollow sections, which constitute the pen-stock of the pump. A isthe upper section or body of the pump; B, a metallic section; and C, afoot-stock or bottom section.

The metallic section or length' B is constructed With outwardly-flaring ends a a', adapted for receiving, and havin g tightly tted into them, the tapered ends of the two wooden sections A and C, thus" connecting the threey sections firmly together. V

The metallic section B is made slightly longer than the length of the stroke required to give the piston D, so that this piston shall work freely up and down between the ends of the two wooden sections A and C; and-the y internal diameter of the said metallic section is equal to the external diameters of the Wooden sections at `their reduced ends. This will, of

course, afford a chamber for the piston to work in, which is of greater diameter than the diameterof the interior bore of the wooden section A.

The section B is lined upon its inner side With a vitreous substance onenamel, applied in the usual Well-known manner of enameling metallic surfaces, Which'will present a smooth surface to the piston-packing that will last for years Without requiring a removal. Not only will a smooth, durable surface be afforded in this Way, but it will be seen that the piston will not be caused to bind and work tight in the metallic section, a difiiculty often experienced in wooden pumps, owing to the contraetion of the wood.

I am aware that it is not new to line or inclose within a pump-stock avitre'ous substance to prevent undue wear upon the piston-paek ing; but I am not aware that such feature has ever been employed in combination with a metallic section, which is adapted to receive into its iiaring ends the wooden sections of the pump-stock, and unite these sections together so as to constitute a part of the length of such stock, and afford an enlarged pistonchamber. This flaring and vitreous-lined section B will allow the wooden sections A G to be Vseparated at pleasure, for obtaining access to the piston and valves and vfor renewing or repairing -tliese sections.

The piston consists of a ring, D, having a packing, b, of india-rubber or other suitable material, confined in a groove made in its circumference, and an annular rib or raised valve-seat, o, formed upon its upper side.

A bridge, h, extends diametrically across the opening through the ring D, and from the center of this bridge rises a short pistonfrod, ,having its upper end forked as at c, for receiving and\having secured to it the rod J, by which the piston is moved up and down.

The stem or valve-rod 'i receives loosely upon it a circular flatface' valve, g, which is allowed to rise and fall freely,l and which will, by' fitting snugly upon its seat r, prevent Water from passing through the piston during its ascent. The enlargement of rod i, produced by the .forked portion c, will prevent valve gfrom rising too high during the descent of the piston. The piston-ring,its valve, and the stem or rod i are prevented from'rusting by having these parts galvanized. The packing b, if of india-rubber, is drawn over one of the flanges of the piston-ring, and allowed to contract and ll the groove formed in the periphery of this ring. The valve S, which is applied to the upper end of section C, may be made in the usual Well-known manner for preventing the fall of the Water lifted into section B.

From the foregoing description it will be seen that the three sections of the pen-stock will be firmly united, when forced together, by reason of the pliable character of the Wooden sections Which enter the metal section, and also by reason of the Wedgin g form of the entering ends thereof. This also will be increased when the Wood expands and becomes soft under the influence of moisture or Water.

I do not claim a cylinder of glass bound at its top and bottom by metal pieces Which are held together by rods; nor do I claim a stonebottom section lined with copper; nor do I claim a metal section lined with copper; but

What I do claim as my invention, and desire to secure by Letters Patent, is-

l. The metal-tube section B, coated with a vitreous substance, and constructed with Haring ends, and receiving into said, ends the lower terminus of the Wooden section A and the upper terminus of the lower Wooden section, B, all substantially as described.

2. An annular-grooved ring-piston, D, constructed with a raised valve-seat, c, and a forked stem, i c, in combination with valve g, substantially as described.
